Orchids are amazingly beautiful plants, seemingly exotic and often surrounded by an air of mystery. They’ve taken on a bad reputation of being difficult to grow, requiring a lot of work and maintenance, but the good news is, they are actually hardy plants that aren’t any more challenging to care for than other flowering ornamentals. Their care is just different.
There are many varieties of orchids available for purchase, and yes, some are fussy, but many are extremely adaptable to the light and temperature conditions found on the windowsills of homes and apartments. One of most important aspects of caring for them, is to replant/repot them frequently. Using these following tips, you’ll be rewarded with healthy, beautiful plants that can be coaxed to bloom repeatedly.
1. Repot every 1-2 years
Unlike many of the other flowering ornamental plants, orchids do not grow in potting soil. They are grown in loose, chunky, potting substrates such as bark, charcoal, or moss; the only need the growing media to anchor themselves to. This means plants need to be repoted when their growing media begins to break down, or the roots start coming out of the top of the pot. According to the American Orchid Society, repoting is done with the root system in mind, not the foliage.
2. Transplant after flowering
There isn’t a specific time of year, or season, that is best for replanting/repotting an orchid. Instead, it’s best to time this transition to a larger container just after the plant has finished flowering and new growth is beginning to emerge.
3. Slightly increase container size
Look for a new container that is only slightly larger in size. Choose a pot that is orchid specific — they are perforated for air movement — or opt for terra cotta or plastic that has plenty of drainage. Increase container size by 1 – 2″ in diameter at most.
4. Do not use potting “soil”
In their native habitat, orchids attach themselves to other plants instead of growing in the ground. To give them a similar environment for growing use a potting/growing media recommended for orchids specifically. Some of the preferred substrates are fir bark, coconut coir, and sphagnum moss.
5. Soak container prior to transplanting
To make it easier to remove the orchid from its current home, soak the pot in water for a couple of hours prior to replanting it.
6. Add moisture to new potting mix
In a separate, clean container add boiling water to the potting mix for the new pot and allow to sit for a sit until the water comes to room temperature. Gardenista recommends adding about twice as much water as potting mix, and then draining the excess off.
7. Sterilize all tools
Orchids are very susceptible to disease and fungus. Before beginning this project thoroughly clean and sterilize any tools you will be using such as scissors, a garden trowel, etc. One of the easiest and quickest ways to disinfect tools is to wipe them down with a 70% iso propyl alcohol solution and allow to air dry.
8. Remove orchid from container
Gently extricate the orchid and potting mix from the old container, being careful to not damage the plant’s roots using too much force.
9. Loosen potting mix from roots
Using your hands, remove as much of the growing media from the roots as possible. Carefully untangle the mass of roots from one another as well.
10. Clean up roots
Using sterilized clippers or scissors, remove any dead or diseased roots, as close to the plant as possible. This will allocate plant resources to healthy tissues instead of the orchid trying to “feed” the problem areas to nurture them back to health.
11. Repot into new container
Add a shallow layer of potting media to the bottom of the container. Place the orchid in the pot, so the crown is level with the top, and then fill in all of the empty space with bark, or whatever media you are using. Use your fingers or chopsticks to gently settle it in around the roots.
12. Add support stake
Once your orchid is nestled securely in its larger home, care for it as you did in the past, including staking it to provide support. Source
